main.py# 打开文件 MyFile.txt，写入数据
nameHandle = open('MyFile.txt', 'w')
nameHandle.write('one\n')
nameHandle.write('two\n')
nameHandle.close()
# 打开文件 MyFile.txt，读取数据
nameHandle = open('MyFile.txt', 'r')
for line in nameHandle:
print(line[:-1])
nameHandle.close()
# 打开文件 MyFile.txt，在文件尾端写入数据
nameHandle = open('MyFile.txt', 'a')
nameHandle.write('three\n')
nameHandle.write('four\n')
nameHandle.close()
# 打开文件 MyFile.txt，读取数据
nameHandle = open('MyFile.txt', 'r')
for line in nameHandle:
print(line[:-1])
nameHandle.close()
结果：
MyFile.txtone
two
three

main.py
students = {'a': 89, 'b': 60, 'c': 45, 'd': 90, 'e': 95}
FILE = open('grade.txt', 'w')
for each in students.items():
name, score = each
FILE.write(f"{name} {score}\n")
FILE.close()
# --------------------- 这是分界线 ---------------------
FILE = open('grade.txt', 'r')
for line in FILE:
name, score = line.split()
if int(score) > 80:
print(f"{name} {score}")
FILE.close()结果：
grade.txta 89
b 60
c 45
d 90
e 95
打印结果：
a 89
d 90
e 95
